RooMinuit: "CONtour" or "MNContour"?

Dear Experts,
I would like to know the answer to the following very simple question:
the member function “contour” of the ROOT class RooMonuit
performs a “CONtour” or a “MNContour” plot ?

( where the definitions of “CONtour” and “MNContour” plots are on the MINIUT manual )

Many thanks for your support.
